Roof collapses during St. Paddy's Day celebrations in Ontario

ONTARIO, Canada (KTRK) -- It was a scary scene in Ontario after a roof collapsed during St. Patrick's Day celebrations.

Video shows the collapse unfolding while about 40 college students were partying on top of an abandoned house Saturday.

No one was seriously hurt, but a woman sitting on the roof scraped her leg after it got stuck in some of the debris, according to a Canada report.
